What is the normal range for central venous pressure (CVP)?

The normal range for central venous pressure (CVP) is generally accepted as being between 2 to 6 mmHg. This measurement provides an estimate of the right atrial pressure and is important in assessing a patient's fluid volume status and cardiac function. A CVP within this range indicates adequate venous return and right heart filling pressures, thus guiding clinicians in managing patients, particularly those in critical care settings.

While some sources may describe the upper limit of normal CVP as reaching 8 mmHg, option B closely aligns with the standard clinical reference of 0-6 mmHg, which reflects the typical physiological range considered appropriate for effective monitoring of cardiac and fluid status. This information is crucial for the effective management of patients, especially in acute care environments where proper tracking of hemodynamic status can significantly impact treatment decisions.
